Description

Technical Field

[0001] This utility model relates to the field of carbon fiber tube production technology, specifically a mold for producing carbon fiber tubes with multiple specifications. Background Technology

[0002] Carbon fiber tubes, also known as carbon fiber tubes or carbon tubes, are made by pre-impregnating carbon fiber composite materials with styrene-based polyester resin and then heating and curing them through pultrusion (winding). During the manufacturing process, various profiles can be produced using different molds, such as carbon fiber round tubes of different specifications, square tubes of different specifications, sheets of different specifications, and other profiles. 3K coating can also be used for surface packaging and beautification during the manufacturing process.

[0003] In the production process of carbon fiber tubes, the cut carbon fiber sheets need to be wound into shape using a tube winding machine. The tube winding machine needs to be used with a tube winding mold shaft to ensure the shaping diameter of the carbon fiber tube. The existing tube winding machine requires multiple tube winding mold shafts, and it is impossible to produce carbon fiber tubes of multiple sizes with a single tube winding mold shaft. It also occupies a lot of space when stored, so it needs to be improved. Utility Model Content

[0006] The main tube assembly includes a rod body, a first tube sleeve is fitted on the outer wall of the rod body, a second tube sleeve is fitted on the outer wall of the first tube sleeve, and slots are provided on both sides of the second tube sleeve, the first tube sleeve and the rod body, and connecting rods are inserted into the slots.

[0007] Preferably, the connecting rod has a slot on one end and a groove on the bottom, with a telescopic rod and a support spring fixedly connected inside the groove.

[0008] Preferably, a support spring is sleeved on the outer wall of the telescopic rod, and a movable wheel is connected to the lower end of the support spring and the telescopic rod. The movable wheel and the connecting rod form a telescopic connection.

[0009] Preferably, the diameters of the second sleeve, the first sleeve, and the rod decrease sequentially, and the rod is fixedly connected to handles at both ends.

[0012] Preferably, the limiting rod corresponds to the slot of the connecting rod, and the limiting rod is inserted into the slot of the connecting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This device can roll carbon fiber tubes of multiple sizes through the tube mold assembly, which reduces the difficulty of changing molds and improves the efficiency of mold changing.

[0015] (2) This device can accommodate the rolling of three sizes of carbon fiber tubes by fitting a first tube sleeve on the outer wall of the rod body, and fitting a second tube sleeve on the outer wall of the first tube sleeve. This facilitates replacement while reducing the space occupied by the device.

[0016] (3) This device can quickly connect or separate the second sleeve, the first sleeve and the rod by inserting connecting rods at both ends of the second sleeve, the first sleeve and the rod, thereby facilitating the disassembly or installation of the second sleeve, the first sleeve and the rod and improving work efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This utility model provides a technical solution: a multi-specification adaptable carbon fiber tube production mold, including a tube mold assembly 1, the tube mold assembly 1 including a main tube winding assembly 11, a slot is opened on the end side of the connecting rod 17, a groove is opened on the bottom side of the connecting rod 17, a telescopic rod 15 and a support spring 16 are fixedly connected inside the groove, the support spring 16 is sleeved on the outer wall of the telescopic rod 15, and a moving wheel 18 is connected to the lower end of the support spring 16 and the telescopic rod 15. The telescopic rod 15 is a telescopic structure composed of a sleeve and a rod. By setting the telescopic rod 15, the support spring 16 can be limited without affecting the extension and retraction of the support spring 16. The moving wheel 18 and the connecting rod 17 form a telescopic connection. The length of the connecting rod 17 is greater than that of the second sleeve 13. The second sleeve 13, the first sleeve 12, and the groove on the outer wall of the rod body 111 facilitate the removal of the connecting rod 17 from the second sleeve 13, the first sleeve 12, and the rod body 111. This structure, through the support spring 16, allows the bottom of the support moving wheel 18 to abut against the outer wall of the first sleeve 12 and the rod body 111 when the connecting rod 17 is inserted into the second sleeve 13, the first sleeve 12, and the rod body 111. The moving wheel 18 makes insertion and removal of the connecting rod 17 easier. The main tube assembly 11 includes a rod body 111, with the first sleeve 12 sleeved on the outer wall of the rod body 111. The wall sleeve includes a second sleeve 13. The diameters of the second sleeve 13, the first sleeve 12, and the rod 111 decrease sequentially. Rod handles 112 are fixedly connected to both ends of the rod 111. This structure allows workers to easily place the device onto the tube winding machine via the rod handles 112. Grooves are formed on the second sleeve 13, the first sleeve 12, and the rod 111. These grooves are annular in structure, with the annular grooves located in the middle for limiting the movement of the carbon fiber tube sheet during winding. Limiting rods 14 are provided at both ends of the rod 111 and the first sleeve 12. The limiting rods 14 are rotatably connected to the rod 111 and the first sleeve 12 via a rotating shaft. This structure facilitates… The limiting rod 14 is rotated, and the limiting rod 14 corresponds to the slot of the connecting rod 17. The limiting rod 14 is inserted into the slot of the connecting rod 17. This structure can achieve quick connection or separation with the connecting rod 17 by rotating the limiting rod 14. When connected with the connecting rod 17, it can restrict the left and right movement of the connecting rod 17 and prevent the connecting rod 17 from detaching from the second sleeve 13, the first sleeve 12 and the rod body 111. When separated from the connecting rod 17, the second sleeve 13, the first sleeve 12 and the rod body 111 can be disassembled. The second sleeve 13, the first sleeve 12 and the rod body 111 all have slots on both sides, and the connecting rod 17 is inserted into the slots.

[0025] Working principle: When using this multi-specification adaptable carbon fiber tube production mold, firstly, when using the second sleeve 13 to roll the carbon fiber tube sheet, the worker directly attaches the carbon fiber tube sheet to the outer wall of the second sleeve 13, and then places the tube mold assembly 1 inside the tube rolling machine for processing. If the first sleeve 12 is needed, the second sleeve 13 is disassembled. During disassembly, the limiting rod 14 connecting the second sleeve 13 and the first sleeve 12 is rotated to separate the limiting rod 14 from the connecting rod 17. Then, the connecting rod 17 can be pulled out from inside the second sleeve 13 and the first sleeve 12. If the rod body 111 is needed, the limiting rod 14 connecting the rod body 111 and the first sleeve 12 is rotated to separate the limiting rod 14 from the connecting rod 17. Then, the connecting rod 17 can be pulled out from inside the connecting rod body 111 and the first sleeve 12.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
